MATLAB programmer

I have worked with MATLAB for 9 years. Most recently I use MATLAB daily during my postdoctoral work, for data analysis and software interfacing. I also assisted in tutorials of large groups of Engineering Masters students who were learning MATLAB. My experience of other programming languages (C++, Java, Processing, Fortran) gives me a good background that helps improve my script writing performance. Skill sets: Bayesian inferencing, nonlinear Kalman filters Data analysis (e.g. Fourier, wavelet, correlation, regression) Modelling physical processes (e.g. diffusion modelling using finite differences method) Teaching (MATLAB, mathematics, space systems) Unfortunately I cannot do homework assignments. However, I am very interested in working with start-ups and small businesses, as well as in scientific collaborations.

Experience

Consultant

Self Employed
Dec 2014 - Present
I work with small businesses and start-ups to develop nonlinear Bayesian inferencing and sensor fusion algorithms. Applications involved tracking of satellites by shipborne antennas, development of a next-gen satnav system, inference of unknown terms from biological models and improving the profitability of financial trading algorithms.

Dispersion relation of electromagnetic ion cyclotron waves using Cluster observations

Annales Geophysicae
Multi-point wave observations on Cluster spacecraft are used to infer the dispersion relation of electromagnetic ion cyclotron (EMIC) waves. In this study we use a phase differencing method and observations from STAFF and WHISPER during a well-studied event of 30 March 2002. The phase differencing method requires the knowledge of the direction of the wave vector, which was obtained using minimum variance analysis. Wave vector amplitudes were calculated for a number of frequencies to infer the disper

Simulation of high-energy radiation belt electron fluxes using NARMAX-VERB coupled codes

Journal of GeophysicalResearch: Space Physics
This study presents a fusion of data-driven and physics-driven methodologies of energetic electron flux forecasting in the outer radiation belt. Data-driven NARMAX (Nonlinear AutoRegressive Moving Averages with eXogenous inputs) model predictions for geosynchronous orbit fluxes have been used as an outer boundary condition to drive the physics-based Versatile Electron Radiation Belt (VERB) code, to simulate energetic electron fluxes in the outer radiation belt environment. The coupled system has been tested
